Cosmetic method using a composition containing siloxane resins and powder dye

ABSTRACT

The invention relates to a cosmetic method for making-up and/or caring for keratin materials, whereby a cosmetic composition is applied to the keratin materials, in particular the skin and lips, preferably the skin, said cosmetic composition comprising siloxane resins and a powder dye that has been surface treated with a hydrophobic agent. In particular, the invention relates to compositions used to care for or make-up the aforementioned keratin materials.

The invention relates to a cosmetic method for making up and/or caringfor keratin materials, comprising the application to said keratinmaterials, in particular the skin, the lips and preferably the skin, ofa cosmetic composition comprising siloxane resins and a pulverulentdyestuff that has been surface-treated with a hydrophobic agent. Theinvention relates in particular to compositions for caring for or makingup said keratin materials.

According to the invention, the term “keratin materials” is intended todenote the skin of the body and the mucous membranes, for example theface or the lips.

It is known practice to use makeup products in order to give the skincolor. These products usually contain pigments (in particular ironoxides and titanium oxides) which make it possible to obtain a certaincoverage. Once applied to the skin, after application, this productshould have good staying-power properties, in particular good stayingpower of the color, the mattness and the uniformity, and the makeupshould not be sensitive to rubbing. After makeup has been applied, thesebum secreted by the skin over time modifies the cosmetic properties ofthe makeup result. In particular, sebum has a tendency to modify thecolor of makeup deposited on the skin; this color modification goesagainst the color esthetic effect desired, since the visual appearanceof the makeup no longer corresponds to the initial color of thecomposition that was chosen. This poor staying power of the color of themakeup over the course of the day therefore requires said makeup to bere-applied in order to preserve a uniform makeup result.

In order to improve this staying power, polymers which provide stayingpower over the course of the day are used. These polymers are of verydifferent chemical nature and are carried either in a fatty phase or inan aqueous phase (for example, silicone resins, polyacrylates, latexes,etc.).

While these polymers actually provide staying-power properties, inparticular transfer-resistance properties, they do not always make itpossible to obtain staying power of the color throughout the day(problem of resistance to the secretion of sebum and water).

It is therefore necessary to find a technical solution which makes itpossible to obtain these color staying-power properties.

The objective of the present invention is therefore to provide acosmetic method for caring for and in particular for making up keratinmaterials, which makes it possible to obtain cosmetic properties thatare satisfactory immediately and over time, in particular which makes itpossible to obtain staying power over time of the initial color, of themattness and/or of the uniformity of the makeup.

This objective, and also others, are achieved by means of the presentinvention which describes in particular a cosmetic method for making upand/or caring for keratin materials, comprising the application, to saidkeratin materials, of a composition comprising, in a physiologicallyacceptable medium:

MQ resins that are suitable for use as component a), and also themethods for the production thereof, are known in the prior art. U.S.Pat. No. 2,814,601, belonging to Currie et al., of Nov. 26, 1957,incorporated into the present document by way of reference, describes amethod for the production of MQ resins by conversion of a water-solublesilicate into a silicic acid monomer or a silicic acid oligomer using anacid. Once the appropriate polymerization has been carried out,trimethylchlorosilane ends are introduced in order to obtain the MQresin. Another method for preparing MQ resins is described in U.S. Pat.No. 2,857,356 belonging to Goodwin, of Oct. 21, 1958, incorporated intothe present document by way of reference. Goodwin describes a method forthe production of an MQ resin by cohydrolysis of a mixture of an alkylsilicate and an organopolysiloxanetrialkylsilane which is hydrolysable,with water.

The MQ resins that are suitable as component a) in the present inventioncan contain D and T units, provided that at least 80 mol %, or even 90mol %, of the total siloxane units are M and Q units. The MQ resins canalso contain residual hydroxyl groups as is mentioned above. The MQresins can also comprise additional ends, residual hydroxyl groupsbeing, for this, reacted with suitable M groups.

The propyl T resin b) according to the invention comprises at least 80mol % of (R″SiO_(3/2)) units in which R″ independently represents analkyl group containing from 1 to 8 carbon atoms, an aryl group, acarbinol group or an amino group, with the condition that at least 40mol % of the R″ groups are propyl groups.

Preferably, the propyl T resin according to the invention is such thatat least 50 mol % of the R″ groups are propyl groups, preferably atleast 90 mol %.

Preferably, the propyl T resin b) is film-forming. The term“film-forming resin” is intended to mean a resin capable of forming, byitself or in the presence of an auxiliary film-forming agent, a filmwhich is macroscopically continuous and adherent to keratin materials,and preferably a cohesive film, and even better still a film of whichthe cohesion and the mechanical properties are such that it is possiblefor said film to be isolated and to be handled in isolation, for examplewhen said film is produced by pouring onto a non-stick surface such as aTeflon-coated or silicone-coated surface.

The definition of the R″ radical is the same as that of the R′ radical.The definitions mentioned above that are applicable to R′ are thusapplicable to R″.

The propyl T resin b) according to the invention is a silsesquioxaneresin. Silsesquioxane resins are well known in the prior art and aregenerally obtained by hydrolysis of an organosilane comprising threehydrolysable groups, such as halogen or alkoxy groups, present in themolecule. The propyl T resin b) can thus be obtained by hydrolysis ofpropyltrimethoxysilane, propyltriethoxysilane or propyltripropoxysilane,or by cohydrolysis of the abovementioned propylalkoxysilanes withvarious alkoxysilanes. As examples of these alkoxysilanes, mention maybe made of methyltrimethoxysilane, methyltriethoxysilane,methyltriisopropoxysilane, dimethyldimethoxysilane andphenyltrimethoxysilane. Propyltrichlorosilane can also be hydrolyzedalone, or in the presence of alcohol. In this case, the cohydrolysis canbe carried out by adding methyltrichlorosilane, dimethyldichlorosilane,phenyltrichlorosilane or similar chlorosilanes andmethyltrimethoxysilane, methyltriethoxysilane, methyltriisopropoxysilaneor similar methylalkoxysilanes. As alcohols that are suitable for thispurpose, mention may be made of methanol, ethanol, n-propyl alcohol,isopropyl alcohol, butanol, methoxyethanol, ethoxyethanol or similaralcohols. As examples of hydrocarbon-type solvents that can be usedsimultaneously, mention may be made of toluene, xylene or similararomatic hydrocarbons, hexane, heptane, isooctane or similar linear orpartially branched, saturated hydrocarbons; and also cyclohexane orsimilar aliphatic hydrocarbons.

The propyl T resins b) according to the invention may contain M, D and Qunits, provided that at least 80 mol %, or even 90 mol %, of the totalsiloxane units are T units. The propyl T resins may also containresidual hydroxyl and/or alkoxy groups, as is mentioned above.

The composition according to the invention also comprises aphysiologically acceptable medium. The term “physiologically acceptablemedium” is intended to mean a medium that is compatible with the skin,the mucous membranes and the skin integuments.

This medium may comprise at least one volatile silicone or organicsolvent, this solvent preferably being compatible with the resins a) andb) and compatible with cosmetic use.

As volatile silicone solvent, mention may be made of cyclicpolysiloxanes, linear polysiloxanes and mixtures thereof.

As volatile linear polysiloxanes, mention may be made ofhexamethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane,tetradecamethylhexasiloxane and hexadecamethylheptasiloxane.

As volatile cyclic polysiloxanes, mention may be made ofhexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane,decamethylcyclopentasiloxane and dodecamethylcyclohexasiloxane.

The organic solvent may also be an alcohol, for instance ethanol,isopropanol, butanol, n-propanol; a ketone, for instance acetone, methylethyl ketone, or methyl isobutyl ketone; an aliphatic hydrocarbon, forinstance heptane, hexane, octane or isododecane, or a glycol ether, forinstance propylene glycol methyl ether, dipropylene glycol methyl ether,propylene glycol n-butyl ether, propylene glycol n-propyl ether, orethylene glycol n-butyl ether.

The mixture of resins a) and b) may be obtained from each of the resinsin solution in a solvent.

In general, at the end of synthesis of the MQ resin according to theinvention, this resin is obtained directly in solution in xylene.

Likewise, at the end of synthesis of the propyl T resin b) according tothe invention, this resin is obtained in solution in toluene.

Each of these resins in solution is mixed with the other one accordingto the following protocol:

-   -   1) the two resin solutions are mixed, with stirring, and then        heated, in particular in a reactor or in an autoclave (in order        to be able to carry out the operation optionally under pressure        or, on the contrary, by establishing a partial vacuum), or even        in an extruder optionally equipped with a solvent        “devolatilization” system, under the following specific        conditions:        -   uniform heating is carried out: the heating temperature            should be greater than 90° C., and less than or equal to            250° C., and preferably between 90° C. and 190° C.        -   Either the heating can be carried out at a single            temperature, of between 90° C. and 250° C.,        -   or the heating can be carried out by performing successive            temperature holds:        -   first between 90° C. and T1° C.,        -   T1° C. being a temperature having an intermediate value of            between 90° C. and T2° C. which is the final temperature,        -   for a period of time of between 10 minutes and 2 hours, and            then between T1° C. and T2° C., for a period of time of            between 10 minutes and 4 hours,        -   the temperature T2° C. corresponding to the maximum            temperature chosen for the reaction.        -   This value of T2° C. is variable according to the procedure            chosen and the type of reactor chosen: conventional reactor            or autoclave or extruder, but T2° C. remains less than or            equal to 250° C. It is also possible to perform intermediate            temperature holds between T1° C. and T2° C.;        -   the heating time is at least one hour in a reactor or in an            autoclave and at least 10 minutes in an extruder, preferably            between 1 h and 5 h in a reactor or in an autoclave, and            preferably between 10 minutes and 2 hours in an extruder;        -   provided that these heat treatments are carried out without            the presence of a catalyst for chemical condensation between            the two MQ and propyl T resins. Such a catalyst is in            particular a mineral base, in particular NaOH, KOH or            aqueous ammonia.    -   2) Optionally, after, or even during, step 1) of heat treatment        of the two resins in the temperature range indicated, partial or        total distillation of the aromatic solvents is carried out,        replacing them with a cosmetically acceptable volatile solvent.        Such a volatile solvent may in particular be a volatile        silicone, or not, preferably decamethylcyclopentasiloxane, or a        volatile organic solvent, or not, preferably isododecane.    -   3) Again optionally, after mixing of the two initial solutions        of each resin in a volatile solvent, the mixture of solutions is        treated in a screw or twin-screw blender of “devolatilizing”        extruder type, in a temperature range between 90° C. and 250°        C., making it possible to volatilize the volatile solvents by        establishing a partial vacuum, while working continuously, and        then to pass the molten mixture without solvent through a die.        The molten mixture is then cooled on leaving the die and cut up        in solid granules or in the form of a powder. In this case, the        mixture is directly in solid form and will be redissolved in the        selected solvents at the time of formulation.

Thus, a subject of the present invention is also a method using acomposition as described above, comprising, in a physiologicallyacceptable medium:

1) the mixture of a siloxane resin a) and a propyl silsesquioxane resinb), the mixture being as described above, and

2) at least one pulverulent dyestuff that has been surface-treated witha hydrophobic agent chosen from a compound of fluorinated nature, afatty acid, an amino acid and a mixture thereof,

-   -   mixing, preferably with stirring, a solution of siloxane resin        with a solution of propyl silsesquioxane resin, the solvent        present in each of the solutions preferably being volatile, and        then    -   heating, in particular in a reactor or in an autoclave or in an        extruder, under the following specific conditions:        -   heating is carried out uniformly at a temperature of greater            than 90° C., and less than or equal to 250° C., preferably            between 90° C. and 190° C.; the heating can be carried out            at a single temperature, or at temperature holds, as            indicated above;        -   the heating time is at least 1 hour in a reactor or in an            autoclave and at least 10 minutes in an extruder, preferably            between 1 h and 5 h in a reactor or in an autoclave and            preferably between 10 minutes and 2 hours in an extruder;        -   provided that these heat treatments are carried out without            the presence of a catalyst for chemical condensation between            the two MQ and propyl T resins. Such a catalyst is in            particular a mineral base, in particular NaOH, KOH or            aqueous ammonia.

This method may comprise, after or even during the mixing step, anadditional step of partial or total distillation of the aromaticsolvents, replacing them with a cosmetically acceptable volatilesolvent.

When an extruder is used, this method may comprise, after or even duringthe mixing step, an additional step of partial or total distillation ofthe aromatic solvents, with the mixture exiting directly in the solidstate.

The final step of the heat treatment, or even the heat treatment itself,can be carried out in a blender intended for stirring very viscousmedia, such as:

-   -   a “Z-arm” blender (“Zigma blender”), in particular a Brabender        blender,    -   an extruder-type screw blender, in particular a single-screw        extruder or a twin-screw extruder (with or without a step of        “devolatilization” of the starting volatile solvents) or in a        kneader which makes it possible to devolatilize by establishing        a thin film on the walls.

The term “compound of fluorinated nature” is intended to mean a compoundcomprising at least one fluorine atom.

By way of example, the hydrophobic treatment agent may be chosen fromfatty acids, for instance stearic acid; metal soaps, for instancealuminum dimyristate, the aluminum salt of hydrogenated tallowglutamate; perfluoroalkyl phosphates, poly(hexafluoropropylene oxide)s;perfluoropolyethers; amino acids; N-acylated amino acids or saltsthereof; lecithin, isopropyl titanium triisostearate, isostearylsebacate, and mixtures thereof.

The surface-treated pulverulent dyestuffs can be prepared according tosurface treatment techniques of chemical, electronic, mechanochemical ormechanical nature which are well known to those skilled in the art.Commercial products may also be used.

The surface agent may be absorbed or adsorbed onto the pulverulentdyestuffs by solvent evaporation, chemical reaction and creation of acovalent bond.

According to one variant, the surface treatment consists of a coating ofthe pulverulent dyestuffs.

The coating may represent from 1% to 300% by weight of the weight of theuntreated pulverulent dyestuffs, for example from 5% to 200%, inparticular from 10% to 100% by weight of the weight of untreatedpulverulent dyestuffs.

The coating may represent from 0.1% to 10% by weight, and in particularfrom 1% to 5% by weight of the total weight of the coated pulverulentdyestuff.

The coating can be carried out, for example, by adsorption of a liquidsurface agent at the surface of the pulverulent dyestuffs by simplemixing, with stirring, of said pulverulent dyestuffs and of said surfaceagent, optionally hot mixing, prior to the incorporation of theparticles into the other ingredients of the makeup or care composition.

The coating can be carried out, for example, by chemical reaction of asurface agent with the surface of the pulverulent dyestuffs and creationof a covalent bond between the surface agent and the pulverulentdyestuffs. This method is in particular described in U.S. Pat. No.4,578,266.

The chemical surface treatment may consist in diluting the surface agentin a volatile solvent, in dispersing the pulverulent dyestuffs in thismixture, and then in slowly evaporating off the volatile solvent, insuch a way that the surface agent is deposited at the surface of thepulverulent dyestuffs.

The oily structuring agent may also be chosen from non-polymericmolecular organic gelling agents, also known as organogelling agents,which are compounds whose molecules are capable of establishing betweenthemselves physical interactions leading to self-aggregation of themolecules with formation of a supramolecular 3D network that isresponsible for the gelation of the oil(s) (also known as the liquidfatty phase).

The supramolecular network may result from the formation of a network offibrils (caused by the stacking or aggregation of organogellingmolecules), which immobilizes the molecules of the liquid fatty phase.

The ability to form this network of fibrils, and thus to gel, depends onthe nature (or chemical class) of the organogelling agent, on the natureof the substituents borne by its molecules for a given chemical class,and on the nature of the liquid fatty phase.

The physical interactions are of diverse nature but excludeco-crystallization. These physical interactions are in particularinteractions of self-complementary hydrogen interaction type, πinteractions between unsaturated rings, dipolar interactions,coordination bonds with organometallic derivatives, and combinationsthereof. In general, each molecule of an organogelling agent canestablish several types of physical interaction with a neighboringmolecule. Thus, advantageously, the molecules of the organogellingagents according to the invention comprise at least one group capable ofestablishing hydrogen bonds and better still at least two groups capableof establishing hydrogen bonds, at least one aromatic ring and betterstill at least two aromatic rings, at least one or more ethylenicallyunsaturated bonds and/or at least one or more asymmetric carbons.Preferably, the groups capable of forming hydrogen bonds are chosen fromhydroxyl, carbonyl, amine, carboxylic acid, amide, urea and benzylgroups, and combinations thereof.

The organogelling agent(s) according to the invention is (are) solublein the liquid fatty phase after heating to obtain a transparent uniformliquid phase. They may be solid or liquid at room temperature andatmospheric pressure.

The molecular organogelling agent(s) that may be used in the compositionaccording to the invention is (are) especially those described in thedocument “Specialist Surfactants” edited by D. Robb, 1997, pp. 209-263,Chapter 8 by P. Terech, European patent applications EP-A-1 068 854 andEP-A-1 086 945, or alternatively in patent application WO-A-02/47031.

Mention may be made especially, among these organogelling agents, ofamides of carboxylic acids, in particular of tricarboxylic acids, forinstance cyclohexanetricarboxamides (see European patent applicationEP-A-1 068 854), diamides with hydrocarbon-based chains each containingfrom 1 to 22 carbon atoms, for example from 6 to 18 carbon atoms, saidchains being unsubstituted or substituted with at least one substituentchosen from ester, urea and fluoro groups (see patent application EP-A-1086 945) and especially diamides resulting from the reaction ofdiaminocyclohexane, in particular diaminocyclohexane in trans form, andof an acid chloride, for instanceN,N′-bis-(dodecanoyl)-1,2-diaminocyclohexane, N-acylamino acid amides,for instance the diamides resulting from the action of an N-acylaminoacid with amines containing from 1 to 22 carbon atoms, for instancethose described in document WO-93/23008 and especially N-acylglutamicacid amides in which the acyl group represents a C₈ to C₂₂ alkyl chain,such as N-lauroyl-L-glutamic acid dibutylamide, manufactured or sold bythe company Ajinomoto under the name GP-1, and mixtures thereof.

it being understood that at least one of the radicals R and/or R′ is offormula (III).

The group A may especially be of formula:

with R1 and the *s being as defined above.

In particular, R1 may be a methyl group, which leads to a group A offormula:

In particular, the compounds according to the invention may be in theform of a mixture linked to the fact that A may be a mixture of2,4-tolylene and 2,6-tolylene, especially in (2,4 isomer)/(2,6 isomer)proportions ranging from 95/5 to 80/20.

Thecarbon-based chain may be interrupted with the heteroatom(s) and/or maycomprise a substituent comprising said heteroatom(s); the heteroatomsmay especially form one or more —SiO— (or —OSi—) groups.

Thus, the radical R_(a) may have the structure —(CH₂)n′-CH₃ with n′=0 to17, especially 1 to 12 or even from 1 to 6. In particular, R_(a) may bemethyl, ethyl, propyl or butyl.

It may also have the structure —(CH₂)x-O—(CH₂)z-CH₃ or—(CH₂)x-O—(CH₂)y-O—(CH₂)z-CH₃, with x=1 to 10, preferably 2; y=1 to 10,preferably 2, and z=0 to 10, preferably 0 or 1.

In these radicals, the carbon-based chain may beinterrupted with the heteroatom(s) and/or may comprise a substituentcomprising said heteroatom(s); the heteroatoms may especially form oneor more —SiO— (or —OSi—) groups.

Thus, they may have the structure —(CH₂)m-CH₃ with m=0 to 17, especially1 to 12 or even 2 to 5; in particular, R_(b) and/or R_(c) may be methyl,ethyl, propyl or butyl.

They may also have the structure —O—(CH₂)m′-CH₃ with m′═0 to 5,especially 1 to 4 and in particular methoxy or ethoxy.

and L being as defined above.

Preferably, in these formulae, L is a linear or branched C₁-C₈ alkyleneradical, especially methylene, ethylene, propylene or butylene andespecially n-butylene or octylene, or of formula —CH₂—CH(CH₃)—.

In one particular embodiment, R and R′, which may be identical ordifferent, are both of formula (III).

In another embodiment, one of the radicals R or R′ represents a linear,branched and/or cyclic, saturated or unsaturated C₁-C₃₀ alkyl radical,optionally comprising 1 to 3 heteroatoms chosen from O, S, F and N.

This proves to be particularly advantageous for giving the compounds offormula (I) a universal nature, i.e. enabling them to texture,simultaneously, polar or apolar carbon-based media, linear or cyclicsilicone media, and mixed oils, i.e. partially silicone-basedcarbon-based oils, and also mixtures thereof.

The carbon chain may be interrupted with the heteroatom(s) and/or maycomprise a substituent comprising said heteroatom(s), especially in theform of a carbonyl group (—CO—), one or more hydroxyl radicals (—OH),and/or an ester radical —COOR″ with R″=linear or branched alkyl radicalcontaining 1 to 8 carbon atoms.

with n_(R) being the number of moles of amine NH₂—R and n_(R′) being thenumber of moles of amine NH₂—R′ used to prepare the compound of formula(I).

According to a first embodiment of the invention, R may be chosen fromthe mono-branched radicals of general formula C_(n)H_(2n+1), n being aninteger ranging from 6 to 15, in particular from 7 to 9 or even equal to8.

Thus, the two groups R of the compound of formula (II) may represent,respectively, a group:

According to a second embodiment of the invention, R may be chosen fromthe mono-branched radicals of general formula C_(m−p)H_(2m+1−2p)X_(p), pbeing equal to 1, 2 or 3, preferably equal to 1, m being an integerranging from 6 to 15, preferably from 10 to 14, in particular from 10 to12, or even equal to 11, and X representing sulfur and/or oxygen atoms,in particular oxygen atoms.

Such compounds may be present in the compositions according to theinvention as mixtures with isomers, especially positional isomers on thegroup A, especially in 95/5 or 80/20 proportions.

As emerges from the examples below, the presence of one or the other ofthese radicals in the molecule of general formula (II) proves to beparticularly advantageous for giving a universal nature, within themeaning of the invention, to the corresponding non-silicone bis-ureaderivatives.

As non-limiting representations of the compounds that are mostparticularly suitable for the invention, mention may be made moreparticularly of the following compounds, used pure or as a mixture:

As regards R₂, which is different from R₁, it may be advantageouslychosen from the following groups:

When the ethylenic monomer comprisesseveral optionally conjugated ethylenic bonds, the residual ethylenicunsaturations after the polymerization are generally hydrogenated. Thus,in a known manner, the polymerization of isoprene leads, afterhydrogenation, to the formation of an ethylene-propylene block, and thepolymerization of butadiene leads, after hydrogenation, to the formationof an ethylene-butylene block. Among these polymers that may bementioned are block copolymers, especially of “diblock” or “triblock”type such as polystyrene/polyisoprene (SI), polystyrene/polybutadiene(SB) such as those sold under the name Luvitol HSB by BASF, of the typesuch as polystyrene/copoly(ethylene-propylene) (SEP) such as those soldunder the name Kraton by Shell Chemical Co or of the type such aspolystyrene/copoly(ethylene-butylene) (SEB).

Fatty Phase Gelling Silicone Elastomers

The term “elastomer” is intended to mean a deformable, flexible solidmaterial having viscoelastic properties and in particular theconsistency of a sponge. This elastomer is formed fromhigh-molecular-weight polymeric chains, the mobility of which is limitedby a uniform network of crosslinking points.

The elastomeric organopolysiloxanes used the composition according tothe invention are preferably partially or totally crosslinked. They arein the form of particles. In particular, the particles of elastomericorganopolysiloxane have a size ranging from 0.1 to 500 μm, preferablyfrom 3 to 200 μm and better still from 3 to 50 μm. These particles canhave any shape and, for example, be spherical, flat or amorphous.

When they are included in an oily phase, these elastomericorganopolysiloxanes are converted, according to the amount of oily phaseused, into a product which has a spongy appearance when they are used inthe presence of low contents of oily phase, or into a homogeneous gel inthe presence of higher amounts of oily phase. The gelling of the oilyphase by these elastomers may be total or partial.

Thus, the elastomers of the invention can be conveyed in the form of ananhydrous gel consisting of an elastomeric organopolysiloxane and anoily phase. The oily phase used during the production of the anhydrousgel of elastomeric organopolysiloxane contains one or more oils that areliquid at ambient temperature (25° C.), chosen from hydrocarbon-basedoils and/or silicone oils. Advantageously, the oily phase is a siliconeliquid phase containing one or more oils chosen frompolydimethylsiloxanes with a linear or cyclic chain, which are liquid atambient temperature and which optionally comprise an alkyl or aryl chainthat is pendant or at the end of a chain, the alkyl chain containingfrom 1 to 6 carbon atoms.

The first organopolysiloxane (i) is chosen from polydimethylsiloxanes;it is preferably an α-ω-dimethylvinylpolydimethylsiloxane.

The organopolysiloxane is preferably in a gel obtained according to thefollowing steps:

-   -   (a) mixing of the first and second organopolysiloxanes (i) and        (ii);    -   (b) addition of an oily phase to the mixture of step (a);    -   (c) polymerization of the first and second        organopolysiloxanes (i) and (ii) in the oily phase in the        presence of a catalyst, preferably a platinum catalyst.

According to one embodiment, the crosslinked organopolysiloxane can beobtained by polymeric addition reaction of anorganohydrogenopolysiloxane of formula (I) with an organopolysiloxane offormula (II) and/or an unsaturated hydrocarbon-based chain of formula(III).

According to one variant, the crosslinked organopolysiloxane is obtainedby polymeric reaction of an organohydrogenopolysiloxane of formula (I)with an organopolysiloxane of formula (II).

The R group in the organohydrogenopolysiloxane of formula (I) may be analkyl group containing from 1 to 16, preferably from 10 to 16 carbonatoms. This R group may, for example, be a methyl group, an ethyl group,a propyl group, a lauryl group, a myristyl group or a palmityl group.

The R group in the organohydrogenopolysiloxane of formula (I) may alsobe an aryl group, such as a phenyl or tolyl group.

The R group still in the organohydrogenopolysiloxane of formula (I) mayalso be a monovalent hydrocarbon-based chain comprising a cycloalkylgroup, such as cyclohexyl, or else a hydrocarbon-based chain substitutedwith one, two or more groups chosen from a halogen atom, such aschlorine, bromine or fluorine, and a cyano group, for example anα-trifluoropropyl or chloromethyl group.

In particular, at least 30 mol % of the R groups are preferably methylgroups, and from 5 to 50 mol %, preferably from 10 to 40 mol %, of the Rgroups are a hydrocarbon-based chain containing from 10 to 16 carbonatoms.

Protocol for Instrumental Measurements of the Immediate Color andStaying Power of the Color

A colorimetric measurement of the skin is carried out before and afterapplying makeup by measuring the red, yellow and brightness indices,respectively a*, b*, L*. For each woman, an image is taken using achromasphere, with a definition of 410×410 pixels.

The results are expressed in the following way. The color is quantifiedby the red, yellow and brightness indices analyzed by the camera(respectively a*, b*, L*). The staying power of the color is calculatedby the variation in these variables after the makeup has been worn for 3hours (deltaE94).

More specifically, the measurements are carried out on a panel ofindividuals who are kept in an air-conditioned (22° C.+/−2° C.) waitingroom for 15 min before the beginning of the test. They remove theirmakeup and an image of one of their cheeks is acquired using thechromasphere with a definition of 410×410 pixels. This image makes itpossible to measure the color at T0 before applying makeup.Approximately 100 mg of cosmetic composition are then weighed out into awatch glass and are applied with the bare fingers to the half of theface on which the T0 measurement was carried out.

After a drying time of 15 min, an image of the made-up cheek is acquiredusing the chromasphere. This image makes it possible to measure thecolor immediately after applying makeup (Timm). The models then returnto the air-conditioned room for 3 h. Finally, an image of the made-upcheek after waiting for 3 h is acquired using the chromasphere. Thisimage makes it possible to measure the color after wearing makeup for 3h (T3h).

The results are expressed by calculating the difference (Timm−T0), whichmeasures the effect of the makeup. The difference (T3h−Timm) measuringthe staying power of this effect is then calculated. Each image obtainedusing the camera is made use of in color. The color is quantified by thered and yellow indices, the brightness and the color difference(respectively a*, b*, L and deltaE). The deltaE, dE or else ΔE isdefined as a measurement of difference between two colors. The formulaestablished in 1976 is shown below:

|ΔE*=√{square root over (((L ₁ −L ₂)²+(a ₁ a ₂)²+(b ₁ −b ₂)²)}{squareroot over (((L ₁ −L ₂)²+(a ₁ a ₂)²+(b ₁ −b ₂)²)}{square root over (((L ₁−L ₂)²+(a ₁ a ₂)²+(b ₁ −b ₂)²)}″

where:

-   -   L₁, a₁ and b₁ are the coordinates in the colorimetric space of        the first color to be compared and    -   L₂, a₂ and b₂ those of the second.

Protocol for Instrumental Measurements of the Immediate Mattness and thePersistence of the Mattness

The mattness effect and staying power of the mattness of theapplication, to the skin of a panel of individuals, of the W/O emulsiondescribed above is evaluated. The mattness and the staying power of themattness can be measured by means of the protocol described hereinafter.The mattness of a region of the skin, for example of the face, ismeasured using a polarimetric camera, which is a black and whitepolarimetric imaging system, with which images are acquired in parallel(P) and crossed (C) polarized light. By analyzing the image resultingfrom the subtraction of the two images (P−C), the shine is quantified bymeasuring the mean level of gray of the 5% of shiniest pixelscorresponding to the regions of shine.

More specifically, the measurements are carried out on a panel ofindividuals who are kept in an air-conditioned (22° C.+/−2° C.) waitingroom for 15 min before the beginning of the test. They remove theirmakeup and an image of one of their cheeks is acquired with thepolarimetric camera. This image makes it possible to measure the shineat T0 before applying makeup. Approximately 100 mg of the compositiondescribed above are then weighed out into a watch glass and are appliedwith the bare fingers to the half of the face on which the T0measurement was carried out.

After a drying time of 15 min, an image of the made-up cheek is acquiredwith the polarimetric camera. This image makes it possible to measurethe shine immediately after applying makeup (Timm). The models thenreturn to the air-conditioned room for 3 h. Finally, an image of themade-up cheek after waiting 3 h is acquired with the polarimetriccamera. This image makes it possible to measure the shine after wearingmakeup for 3 h (T3h). The results are expressed by calculating thedifference (Timm−T0), which measures the effect of the makeup. Anegative value means that the makeup reduces the shine of the skin andthat it is thus mattifying.

The difference (T3h−Timm) measuring the staying power of this effect isthen calculated. The value obtained should be as low as possible, whichmeans that the mattness of the makeup does not change over time.

Protocol for Instrumental Measurements of the Immediate Uniformity andStaying Power of the Uniformity

A colorimetric measurement of the skin before and after applying makeupis carried out by measuring the means for the planes a*(green-red),b*(blue-yellow), L*(brightness). For each woman, an image is taken usinga chromasphere with a definition of 410×410 pixels. More specifically,the measurements are carried out on a panel of individuals who are keptin an air-conditioned (22° C.+/−2° C.) waiting room for 15 min beforethe beginning of the test. They remove their makeup and an image of oneof their cheeks is acquired using the chromasphere with a definition of410×410 pixels. This image makes it possible to measure the color at T0before applying makeup. Approximately 100 mg of cosmetic composition arethen weighed out into a watch glass and are applied with the barefingers to the half of the face on which the measurement was carried outat T0.

After a drying time of 15 min, an image of the made-up cheek is acquiredusing the chromasphere. This image makes it possible to measure thecolor immediately after applying makeup (Timm). The models then returnto the air-conditioned room for 3 h. Finally, an image of the made-upcheek after waiting for 3 h is acquired using the chromasphere. Thisimage makes it possible to measure the color after wearing makeup for 3h (T3h).

Each image obtained using the camera is made use of by coxellography.The standard deviation of each monochrome plane is calculated. Theproduct of the three standard deviations is equal to the coxellographicindex. This parameter is used for the statistical calculations. The moreuniform the skin, the lower the standard deviation. The coxellographicindex changes in the same way since it is the product of the standarddeviations of the three planes a*, b* and L*.

For the measurements carried out, it is considered that:

-   -   + slight effect or low staying power    -   ++ moderate effect or moderate staying power    -   +++ significant effect or good staying power    -   ++++ very significant effect or very good staying power    -   Compositions    -   Mattness staying power performance    -   Color staying power performance    -   Uniformity staying power performance

Compositions A B C (NAI coating) (PF coating) (Si coating) Mattnessstaying power ++ ++ + performance Color staying power ++++ ++++ ++++performance Uniformity staying power ++++ +++ +++ performance

The compositions exhibit a matting and uniforming effect that issatisfactory, or even very satisfactory for the NAI pigments.

The measurements carried out show that, in terms of overallstaying-power properties (mattness, color and uniformity), the NAIcoated pigments and the PF coated pigments give the best results.

Compositions are reproduced according to this example, in whichcompositions the 60/40 mixture of MQ/propyl T resins according toexample 1-h described above is replaced with the mixture of MQ/propyl Tresins according to example 1-f described above, comprising an MQ/propylT weight ratio of approximately 50/50, and similar results are obtainedwith said compositions.
